    Sturdiest surge protector I've seen
    Style: 12ft Cord (Black), Pattern Name: Single
    I was very surprised by the quality of this surge protector, especially for the price I payed. Pros: Sturdy construction, and nice color. It's barely visible under my desk. Very tight grip on whatever is plugged in so there is no risk of anything accidentally coming unplugged. Thick gauge cord but surprisingly pliable so it bends easily for hiding and bundling up excess length. Visible and satisfying LED light shows your electronics are protected. Guarantee printed right on the box insuring your electronics in case of a damaging power surge. Cons: Nothing that comes to mind! I would strongly recommend this surge protector to anyone looking to manage lots of plugs for a computer, a large entertainment center or just a group of electronics plugged into the same outlet. I know it seems silly to be so enthusiastic over something as trivial as a surge protector but when it comes to protecting large investments you shouldn't put faith in a $5 bargain power strip. I'm buying Tripp Lite any time I need more outlet space from now on!

    Does the trick well.
    Style: Base Station Mount + Headphone Hanger, Style: Base Station Mount + Headphone Hanger
    It's about 3D printer feel, so be sure to locate it where you won't bump it. It comes with everything you need to mount in a couple different configurations, which is a nice touch. The DAC fits perfectly and sets up nicely. Recommended for a polished look to keep your desk clear.

    This item is exactly what you expect by description.
    Style: Base Station Mount + Headphone Hanger
    Magnetic is plenty strong enough to hold headphone up. Works exactly as you would hope. Permanent mounting options included.

    It works and the magnet is strong.
    Style: Base Station Mount + Headphone Hanger
    Strong magnet, looser fit than I like. Once I hang my headphones on the hanger it weighs it down enough to make the tab in the back not do it's job of keeping the base station from slipping out. I squeezed/pinched/bent the plastic together and it is working for now, but the plastic is flexible and I have a feeling I will be doing this again or needing to put some sort of support on the back. It came with a prybar, so I assumed it would be a tighter fit. Not so much.
